Stroke is a serious medical condition that requires immediate attention. It occurs when blood flow to the brain stops, causing brain cells to die within minutes. While not all strokes are fatal, they are a leading cause of death and disability, particularly in older adults. The risk of having a stroke increases with age, but they can occur at any age. The chances of survival are greater when emergency treatment is provided quickly, ideally within 3 hours of the first symptom.

What You'll Learn
Stroke risk increases with age, but can occur at any age
Stroke risk increases with age, but it can occur at any age. While strokes are much more common in older adults, they are becoming more prevalent in younger people. The number of strokes in people aged 18 to 45 has been growing faster nationally than in any other age group over the past few decades. In 2020, about 5% of people who had strokes at UCHealth Poudre Valley Hospital in Fort Collins were aged 18-45, but by July 2023, this had risen to 9%.
Sedentary lifestyles, poor diet, and stress are contributing to the rise in strokes among young people. Working from home means people are moving less, and convenience foods are often high in salt, sugar, and fat, contributing to high blood pressure and cholesterol, two of the biggest risk factors for strokes. Stress, COVID, lifestyle, and diet are all factors in the increase in strokes among people in their 30s, 40s, and even 20s.
Some rare conditions can predispose people to strokes at a young age, but most risk factors for young adults are similar to those for older adults: high blood pressure, diabetes, high cholesterol, and obesity. These conditions are becoming more and more common among younger Americans.
Strokes happen when the blood supply to the brain is disrupted, killing brain cells. If this happens in a part of the brain that controls the body's automatic 'life support' systems, such as breathing and heartbeat, it can be life-threatening. The faster a stroke is treated, the better the chance of preserving brain tissue and reducing the patient's risk of long-term disability.
It is important for people of all ages to be able to recognize the signs of a stroke. Doctors recommend the "B.E. F.A.S.T." method for stroke identification:
- Balance: Are you experiencing a sudden loss of balance or dizziness?
- Eyes: Do you have any loss of vision?
- Face: Does your face or smile look uneven, or is one side drooping?
- Arm: Is one arm or leg hanging down, or do you feel weak on one side?
- Speech: Are you having trouble speaking, communicating, or understanding others? Is your speech slurred?

Strokes are a leading cause of death and disability
The risk of having a stroke increases with age, but they can and do occur at any age. In 2014, 38% of people hospitalized for strokes were under 65. While it is more common in older people, over 60% of strokes occur in those under 70, and 16% in those under 50. The risk of a first stroke is nearly twice as high for non-Hispanic Black adults than for White adults. Non-Hispanic Black and Pacific Islander adults have the highest rates of death from stroke.
Strokes occur when the blood supply to the brain is disrupted, killing brain cells. If this happens in a part of the brain that controls the body's automatic 'life support' systems, such as breathing and heartbeat, it can be life-threatening. Even when not fatal, strokes can cause serious disabilities, with over half of survivors over 65 experiencing reduced mobility. Other potential consequences include difficulties with eating, speech and language, emotions, and thought processes.
The impact of a stroke on a person's life can be devastating, leading to care and financial challenges for the individual and their caregivers. The global economic impact of stroke is estimated to reach US$1 trillion by 2030. However, strokes are preventable and treatable. Early action is crucial, and the chances of survival are greater when emergency treatment is swift.

The longer the interruption in blood flow, the greater the damage
A stroke occurs when the blood supply to the brain is interrupted, resulting in the death of brain cells. The extent of damage caused by a stroke depends on the duration of the interruption in blood flow. The longer the brain is deprived of oxygen and nutrients, the greater the risk of irreversible brain damage and the more severe the long-term consequences.
When blood flow to the brain is blocked, brain cells begin to die within minutes, leading to permanent brain damage. The first few hours after a stroke are critical, as receiving medical treatment within this time frame can significantly improve the chances of survival and recovery. An interruption in blood flow for more than 10 seconds can cause unconsciousness, and if the blockage persists for a few minutes, it typically results in irreversible brain damage.
The impact of a stroke depends on the area of the brain affected and the duration of the interruption. Focal brain ischemia occurs when a blood clot blocks a cerebral vessel, reducing blood flow to a specific region of the brain. This increases the risk of cell death in that particular area. Global brain ischemia, on the other hand, occurs when blood flow to the brain is halted or drastically reduced, often due to cardiac arrest.
The severity of a stroke is influenced by the duration of the interruption in blood flow. The chances of survival and recovery are higher when emergency treatment is provided promptly. Therefore, recognizing the signs and symptoms of a stroke and seeking immediate medical attention are crucial to minimizing the damage caused by the interruption in blood flow to the brain.

The Risk of a Second Stroke
Suffering a stroke is a serious medical event, and it is the second leading cause of death worldwide. Even after surviving a stroke, the risk of suffering a second one is much higher. In fact, of the 795,000 Americans projected to have a stroke this year, 23% will suffer a second stroke. This risk is highest in the first year after the first stroke, with a risk 15 times greater than the general population.
There are several factors that can increase the risk of a second stroke, including blood clotting, high blood pressure, and heart problems. Therefore, it is crucial to manage these risk factors effectively. This can be achieved through a combination of lifestyle changes and medical treatment. Lifestyle changes such as increasing physical activity, improving sleep habits, eating a healthy diet, and quitting smoking can significantly reduce the risk of a second stroke. Additionally, it is important to take prescribed medications as directed by a doctor to control conditions such as high blood pressure, high cholesterol, and diabetes.
The risk of a second stroke can be mitigated by following a prevention plan recommended by a doctor. This may include managing high blood pressure, controlling cholesterol levels, maintaining healthy blood glucose levels, staying active, improving dietary habits, losing weight, and quitting smoking. It is essential to consult with a doctor to understand the specific steps that can be taken to reduce the chance of another stroke.
According to a study by stroke researchers at Sunnybrook, published in the Canadian Medical Association Journal, individuals who survive a stroke remain at a substantial long-term risk for future strokes. The risk of experiencing another stroke can be doubled for up to five years. This highlights the importance of maintaining risk-reduction strategies, medical support, and healthy lifestyle choices over the long term, even years after the initial event.

Stroke is a type of cardiovascular disease
Stroke is a life-threatening condition that affects the cardiovascular system, which is also known as the circulatory system. It involves the heart and all the blood vessels responsible for pumping and moving blood around the body. When an individual has a stroke, the blood supply to their brain is interrupted, resulting in the death of brain cells. This occurs due to a blockage or the bursting of one or more blood vessels that supply blood to the brain.
Stroke is a leading cause of death and serious long-term disability in the United States, with approximately 159,000 Americans dying from stroke each year. It is the fourth and fifth leading cause of death in New York State and the U.S., respectively. Additionally, stroke is a significant cause of disability, reducing mobility in more than half of stroke survivors aged 65 and older.
The risk of having a stroke increases with age, but it can occur at any stage of life. Certain factors, such as high blood pressure, high cholesterol, smoking, obesity, and diabetes, are leading causes of stroke. Early action is crucial for stroke treatment, as prompt emergency treatment significantly improves the chances of survival and reduces the likelihood of long-term disabilities.
To prevent strokes, individuals can make healthy lifestyle choices, such as consuming nutritious meals, maintaining a healthy weight, avoiding smoking and excessive alcohol consumption, and managing conditions like high cholesterol, high blood pressure, and diabetes. By adopting these habits and seeking regular medical check-ups, the risk of stroke can be significantly reduced.
